In an electrically heated home, the temperature of the ground in contact with a concrete basement wall is 12.3 oC. The temperature at the inside surface of the wall is 20.1 oC. The wall is 0.16 m thick and has an area of 6.1 m2. Assume that one kilowatt hour of electrical energy costs $0.10. How many hours are required for one dollar's worth of energy to be conducted through the wall?
In an electrically heated home, the temperature of the ground in contact with a concrete basement wall is 13.4 °C. The temperature at the inside surface of the wall is 22.1 °C. The wall is 0.16 m thick and has an area of 6.7 m2. Assume that one kilowatt hour of electrical energy costs $0.10. How many hours are required for one dollar's worth of energy to be conducted through the wall? Number Units
Chapter 13, Problem 01 The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 280 J/s. The energy is transferred a distance of 2.1 × 10-3 m through a body whose surface area is 1.8 m2. Assuming that the thermal conductivity is that of body fat, determine the temperature difference between the capillaries and the surface of the skin. Chapter 13, Problem 02 In an electrically heated home, the temperature of the...

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
